Abstract: 120,893. Aktiebolaget Mjolkningsmaskin Omega. Nov. 22, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Valves actuated automatically and intermittently.- A valve device for periodically reversing the direction of flow of gases, and particularly applicable for use as a pulsator for milking - machines, is actuated by a piston reciprocating in a cylinder which communicates with a chamber having a, larger volume than that through which the piston passes. The Figures show the invention applied to a pulsator for a cow-milker. Suction is admitted through a port 16 and, in the position shown, passes by way of port 12<a>, passage 5<a>, and connexions 13<a> to the milking-appliances, and by way of a port similar to the port 14 to a chamber behind the piston A. At the same time, atmospheric air entering at the connexion 11 passes by way of passage 4, and ports 10<b>, 12b to a passage 5<b> connected to the milking-appliances through connexions 13<b> and through a restricted passage 14 to the enlarged chamber beyond the piston B. When the difference of pressure acting on the two pistons is sufficient to overcome the attraction between the magnetized piston B and a soft-iron armature 8, the piston moves to the left. The connexions 13<a> are then connected to atmosphere and connexions 13<b> are connected to suction until the difference of pressure moves the pistons back again. The pistons may be of soft iron, in which case the armatures 8 are replaced by horse-shoe magnets.

Such a system is described in Specification 1,297,071. The transmitter/receiver of a mobile subscriber includes comparison circuitry which compares successively received general call codes from each concentrator channel in turn until a coincidence is obtained when that concentrator channel is adapted for the call. In the system described, the first received call code is stored, suitably in a shift register 17, compared at 17<SP>1</SP> with the subsequently received second and third call codes stored at 21 to provide signals to a counter 23 whenever the stored codes are found to be identical. In the case described if the three codes are the same that concentrator channel is seized for the connection. If they are not identical the receiver is advanced to the next free channel radiating the general call code by pulse J and a further test made. If no coincidence is found after q successive explorations of the N channels the particular concentrator is abandoned. This number of explorations precludes abandonment when transient fading or masking occurs.

Abstract: 715,695. Thermal switches. SUNVIC CONTROLS, Ltd. July 16, 1952 [Aug. 1, 1951], No. 18234/51. Class 38(5) The moving contact 5 of a switch is carried by a bimetal strip 1 and normally engages a fixed contact 6. The strip 1 is secured to a block 3 pivoted at 4 and carrying a strip 2 which may also be bimetallic for ambient-temperature compensation. The strip 2 is coupled at 8 to a bell-crank lever 9 pivoted at 10 and adjustably carrying a lever 11 having a roller 15 co-operating with the upper surface of a lever 16 pivoted at 17 and urged upwards by a spring 18, the pull of which is adjustable. The parts normally occupy the position shown but when the strip 1 is heated by a coil 20. or by the current through it, it tends to deflect downwards. Since its right-hand end is fixed by the contacts 5, 6, the left-hand end only can move to tilt the right-hand end of strip 2 upwards. at the same time increasing the pressure between the contacts. The movement of strip 2 biases the lever 9 clockwise and the roller 15 bears against a step 21 on the lever 16 with increasing force until spring 18 is overcome and lever 9 snaps across to open the contacts rapidly. A similar action occurs in the reverse direction on cooling of strip 1. Contact 5 may be a bridging contact co-operating with two fixed contacts, and the steps on lever 16 may be replaced by shaping portions, Fig. 2 (not shown). The switch may, alternatively, be arranged to remain open until manually reclosed. The manual control comprises a lever 31 pivoted at 30 and having an external control. When the contacts are to be reclosed, lever 31 is moved counter-clockwise so that it moves under a projection 33 on bimetal 1. a portion 32. of the lever at the same time engaging the lever 9 and resetting the snap-action means. Reverse movement of lever 31 then allows the contacts to reclose. The functions of bimetals 1, 2 may be interchanged.
